elementdef
The <elementdef> element identifies
an element on which an attribute is enumerated. When the <elementdef>
is left out of an <enumerationdef> element,
the enumeration is bound to the attribute in all elements.

Example
In this example, the <lomDifficulty> element has been specialized from the <data> element. The value attribute on the <lomDifficulty> element (but not the value attribute on other elements) is bound to a specific set of values. This means that processors should limit that attribute on that element to the values veryEasy, easy, medium, difficult, or veryDifficult.
<subjectScheme>
<subjectdef keys="difficulty">
<subjectdef keys="veryEasy"/>
<subjectdef keys="easy"/>
<subjectdef keys="medium"/>
<subjectdef keys="difficult"/>
<subjectdef keys="veryDifficult"/>
</subjectdef>
...
<enumerationdef>
<elementdef name="lomDifficulty"/>
<attributedef name="value"/>
<subjectdef keyref="difficulty"/>
</enumerationdef>
</subjectScheme>Attributes
| Name | Description | Data Type | Default Value | Required? |
|---|---|---|---|---|
| name | Defines the element for which an attribute enumeration is defined. | CDATA | #REQUIRED | Yes |
| id-atts attribute group (id, conref, conrefend, conaction, conkeyref) | A set of related attributes, described in id-atts attribute group | |||
| status | The modification status of the current element. | new | changed | deleted | unchanged | -dita-use-conref-target | #IMPLIED | No |
| translate | Indicates whether the content of the element should be translated or not. The DITA architectural specification contains a list of each OASIS DITA element and its common processing default for the translate value. | yes | no | -dita-use-conref-target | #IMPLIED | No |
| base | A generic attribute that has no specific purpose. It is intended to act as a base for specialized attributes that have a simple value syntax like the conditional processing attributes (one or more alphanumeric values separated by whitespace), but is not itself a filtering or flagging attribute. The attribute takes a space-delimited set of values. However, when acting as a container for generalized attributes, the content model will be more complex; see Attribute generalization for more details. | CDATA | #IMPLIED | No |
| global-atts attribute group (xtrf, xtrc) | A set of related attributes, described in global-atts attribute group | |||
| class, outputclass | Common attributes described in Other common DITA attributes |
